What is this?

A car loan calculator helps you estimate your monthly auto loan payment and understand the total cost of financing a vehicle. It factors in your down payment, trade-in value, sales tax, and fees to show your true borrowing cost.

How to use

Enter the vehicle price, your down payment and trade-in value (if any), interest rate, and loan term. The calculator shows your monthly payment, total interest, and a payment schedule. Sales tax and fees are added to the loan amount.

Tips

  • Put down 20% for new cars, 10% for used - reduces monthly payment and avoids being underwater
  • Avoid loan terms longer than 60 months - 72+ month loans often leave you owing more than the car is worth
  • New cars lose 20-30% value in first year - consider certified pre-owned to avoid steep depreciation
  • Dealers mark up interest rates 1-2% above wholesale - get pre-approved from credit union for better rate
  • Check KBB or Edmunds for trade-in value - dealers often lowball trade-ins to offset vehicle discounts
  • Negotiate the vehicle price separately from financing - don't focus only on monthly payment
